TETE (DOUBLE ACTION PISTONSEAL) HYDRAULIEK

product

TETE is a double acting complete piston seal which consists of a steel plate vulcanized with elastomeric nitrile rubber using special production methods. The sealing lips do have Stainless steel springs in order to increase the preload.

PRODUCT ADVANTAGES

  • Good sealing performance at low pressures due to the reason having spring on the sealing lips
  • Long service life
  • Ready to fit complete piston
  • Also used in pneumatic systems

APPLICATION
Short stroke , low pressure hydraulic cylinder and special pneumatic cylinders.

INSTALLATION:

TETE is on the piston rod with wire put fixed with a nut. The nut must be secured. The sliding surface and the cylinder bore is coated with oil that does not come with the shut-off element in the reaction. Take special precautions at the end of the stroke to prevent damage to the sealing lips.

NOTES
For special applications that require high temperatures , TETE can be produced in FPM material

MATERIAL: STEEL / NBR 90 SH / STAINLESS STEEL SPRING
